For those who are wondering, I did get the appropriate permits from the city for my work.I have not done any landscaping at this point, nor have I painted the exterior of the building. 

That aside though, if you were lucky enough to buy some of those apartments/condos downtown in 2010-11 and held on, I bet you're doing well.The statistics on the news here is that wayne county (that encompasses Detroit city proper) property values have come back quite a bit. 

@Eric Baum You will need to go to the Planning Department and find out what the minimum lot size is in the neighborhood, what would be required to split, setbacks required for curb, gutter, sidewalk, landscaping, etc.

Landscaper, to install the drain system for the backyard of the house.Any recommendation will be highly appreciated.Emma Chen

I own a small landscape company and have been doing it for around 25 years now and also am a certified home inspector for close to 5 years. 

And as I prepare an offer package, how can I show statistically how this will benefit him  in the long run over other options such as renovation or selling as is and listing?

Also, in the spreadsheet, do you generally see or recommend having groups of property by life for the year placed in service, for example 27.5 year row for the residence in year 1, 5 year row for a dishwasher and fridge in year 1, and 15 year row for landscaping?  

After working for over 35 years as a registered landscape architect/urban design in nationally recognized multi-displine firms, and master planning residential and mixed-use communities around the world, I decided now is the time to add Real Estate Services as an expertise to my portfolio of experiences.

Just now finishing up cleaning up the new property with new roll up doors, landscaping,  and some paint.  

Which basically pays for maintenance of exterior of property, landscaping and a pool (this is a 70 unit condo complex).
